Wouldn't it be more efficient to store off all relevant simulation = values and replay the engine with the simulation values? (There was a long = thread regarding this issue previously under "Cross platform FP" I believe). If the replay amount is small enough, I supposed you could record = straight video, but I am guessing that you will want to replay a significant = amount of video. Plus, re-simulating for replay will allow you to "enhance" the playback, with different camera angles, focusing on relevant pieces of = the action, and perhaps even enhanced rendering techniques. -----Original Message----- From: gda...@li...
